Abstract: 1423734 Pneumatic conveyers O RUSTERHOLZ 26 March 1973 [25 Oct 1972] 14370/73 Heading B8A A pipeline for conveying incoherent solid material comprises a series of trunk sections, each provided with a valve to close the exit from the section, a vent upstream of the valve for carrying gas and an inlet downstream of the valve for a jet of carrying gas under pressure. In each section, whenever the valve is open, the vent and gas inlet are closed, when the valve is closed the vent and gas inlet are open. The valves of alternate sections are open, so that metered quantities of material are carried from one section to the next by the jet of gas, the valves, vents and inlets then being moved to opposite positions and the material moved to the following section. Material is thus conveyed along the pipeline in stages. In the figure, plate 2 opens the valve and closes the vent 1 when moved outwardly, closes the valve and opens the vent when moved inwards. Inlet 3 of each trunk section may be closed by a valve 4.

Abstract: 860,291. Coating articles by electro-deposition ;  electro-forming. PLATECRAFT OF AMERICA Inc. May 7, 1958 [July 19, 1957], No. 14589/58. Class 41. Articles are coated by electro-deposition by immersing the article as a cathode in an electroplating bath containing a suspension of particles insoluble in the bath and electrically inert, whereby metal is electro-deposited on the article and simultaneously the particles settle on the surface and are embedded in the metal coating and are bonded to it. The metal deposited may be Cr, Cu, Ni, Cd and the article may be pre-coated with one of these. The inert particles are abradant resistant materials, e.g. tungsten or silicon carbide, oxides of iron or alumina, metal carbonates, diamonds or powdered metal preferably in a very fine state of division, e.g. 600 to 1000 U.S.S. sieve. The coating obtained may contain up to 90% of the abradant resistant material. Preferably, the electrolyte and suspended material is circulated by a pump over the article during plating, and the article is also rotated., The process may be used to provide a heat and abrasion resistant surface, e.g, on airplane, locket motor or I.C. engine parts, and to the manufacture of electroformed articles using a mould, e.g. thread gauges, and dies. A suitable coating is 0.0007 inch thick containing 50/50 of nickel and silicon carbide. A final coating of metal only may then be applied. The master mould may be of aluminium, and is removed by dissolving in alkali or acid. Specification 860,290 is referred to.

Patent GB-571159-A (GB)
Title: Improvements relating to moulding
IPC: C08L61/10
Filed: 1943-09-07
Abstract: Moulding stock comprises an ethanol soluble condensation product obtained from phenol and acetaldehyde in approximately equimolecular proportions in presence of an acid catalyst, fibrous asbestos and hexamethylene tetramine in amount not substantially less than one molecular proportion per six molecular proportions of phenol.  The asbestos fibre may be present to about 35-50 per cent of the total weight and about 2 per cent aluminium stearate may be present as lubricant.  The stock is obtained by mixing the asbestos fibre into a solution of the condensation product in ethanol, adding the hexamethylene tetramine and lubricant, removing most of the alcohol, disintegrating the residue and drying.  Methanol or acetone may be used as a solvent. In examples, a thermosetting condensation product obtained from paraldehyde and phenol in presence of hydrochloric acid is mixed with (1) asbestos fibre, hexamethylene tetramine, and aluminium stearate, and (2) is used to impregnate asbestos fabric, together with hexamethylene tetramine and the fabric is then cut into pieces.  Moulding conditions are given.  Reference is made to replacement of the acetaldehyde by formaldehyde, benzaldehyde, or butyraldehyde, and of the phenol by o- or m-cresol.

Title: Improvements in and relating to the production of mixed fertilizers
IPC: C05B11/06
Filed: 1946-05-17
Abstract: Mixed granular fertilisers are produced by reacting, if necessary with heat, mineral rock phosphate, nitric acid, and a water soluble salt of sulphuric acid, the cation of which is not injurious to plants, e.g. ammonium, sodium or potassium, mixing and agitating the resultant damp mixture at a temperature not exceeding 70 DEG  C.  The components may be reacted in pairs in any order, but preferably the acid is added to the mixed phosphate and soluble sulphate.  The solids are preferably finely divided.  Four mols. of 40-70 per cent nitric acid are preferably used per mol. of Ca3(PO4)2 together with an amount required by impurities.  The mixture is preferably stirred at all stages and heated e.g. at 40-70 DEG  C., preferably 50-60 DEG C. during the granulation and a subsequent maturing stage.  Other fertilisers may be incorporated during granulation.  In a continuous process the successive stages may be carried out in two jacketted mixers. The product may be screened and the over-sized material ground and returned with the fines to the process.  The acid solution is preferably added gradually to avoid a wet mixture.  Paddle, drum, planetary or Eirich mixers may be used.  Specifications 148,242, 148,243, [both in Class 1 (iii)], 366,737, 376,793 and 584,866 are referred to.
